public interface GenericVetoableChangeListener<V> extends VetoableChangeListener
A JavaBeans vetoable change listener retrofitted to use generics to cast to proper value type. An implementing class must override the non-generic property change method and call the generic version, so that the property change can be noted by either method. The abstract version of this class, AbstractGenericVetoableChangeListener, will be used most often.
